[GIT PULL] KVM: x86: Pull requests for 7.4

[Sean Christopherson]

This cycle is "fun", only the "mmu" and "svm" requests escaped without a conflict
or some other notable mess.  That said, I don't think there's anything particularly
thorny to deal with, just a lot of minor stuff.  Details in the individual pull
requests.

My apologies for not getting the guest_memfd in-place conversion changes sent
along sooner.  I really wanted to get you a pull request around 7.3-rc4, but we
simply could get the code ready in time.
